The FDA approves the first brain wave test that could help diagnose children and teens with ADHD. Called the NEBA system, the 20-minute test uses an electroencephalogram to calculate the ratio of two brain wave frequencies, called theta and beta, which studies have shown is higher in children and teens with ADHD. The device can be used in patients between the ages of 6 and 17 as part of a complete psychological examination to either help confirm diagnosis or bolster a doctor's decision that more testing is needed.
